SIDNEY J. FINN, OF BEVERLY, MASSACHUSETTS; ASSIGNOR TO UNITED SHOE MACHIN- ERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY roxme APPLYING MACHINE Application filed August 30, 1927. Serial No. 216,399.

This invention relates to machines for use in the manufacture ofboots and shoes and 1s herem Illustrated as embodied in a machine for applying a foxing to the lower.

a margin or'foxing area of a rubber-soled shoe.

In the manufacture of rubber-soled footwear having fabric uppers such as a tennis shoe or an arctic in which the sole is vulcanized to the upper, it is customary, after the 10 shoe has been lasted but beforetheunv-ulcanthe shoe but ensures a tight joint between the upper of the shoe'and the sole.

Hitherto machines for performing opera tions upon the foxing area of a shoe, for example, machines for applying foxing, have required that the shoe be held by the operator and moved in a path to present the foxing area progressively to the operating mechanism. Such machines are not much faster than hand work and necessitate considerable skill on the part of the operator.

The general object of the present invention is to provide an automatic machine for operating upon the foxing area which shall be rapid and accurate and shall do away with the necessity for a skilled operator.

According to one feature of the present invention the shoe is mounted in a holder, and means are provided for producing relative movement between the shoe holder and a member for operating upon the shoe to cause a strip of foxing to'be laid along the foxing area of the shoe. Inthe illustrated machine the shoe is held substantially upright and rotated about a vertical axis while a foxing applying member in the form of a roll is held yieldingly against the foxing area.

Due to the longitudinal curvature of the bottom of the shoe, the foxing area at the heel end of the shoe is at a different level from that at the toe end. According, to another feature of the invention, there is provided means for causing relative movement between the shoe and the operating member heightwise of the shoe at'the proper times during the applying'of the foxing to compensate for this difference in level. In'the illustrated machine, such heightwise movement is produced by causing the shoe to be I rocked forward and back at the proper times.

In orderthat foxing may be applied properly to shoes of different sizes, it is desirable that each shoe, whatever its size, beheld ina certain predetermined relation to the axis about which it-rotates- According, therefore, to another feature of the inventiomfl means are provided for properly positioning each shoe prior to clamping it in place. In

the illustrated machine, in which the upright shoe rotates about a vertical axis, means are provided for engaging the heel and toe ends of the shoe to move the shoe into aposition in which the axis of rotation'passes substantially through the middle of the shoe; and, after the shoe has been sopositioned, it is clamped in the shoe holder.

After the foxing has been applied to the shoe it is desirable to press it firmly into placea'nd to bend its lower portion to some extent over the bottom of the shoe. According to another featureof the invention apresser is provided for this purpose, theillustrated presser being an inflated rubber roll,

the yielding wall of which accommodates itself to the shape ofthe part of the shoe with which, atany given time, it is in engagement.

The upper edgeof thefoxing in the fin- I ished shoe should present a smooth line and not a wavy one. Inorder to ensure that the line shall be a smooth one, irrespective of any unevenness in width which may be present in the-foxing, there is provided, according to another feature of the invention, mechanism for trimming ofl the upper edge of the foxing before the foxing is applied to the shoe. In the illustrated construction this means com-- prises a disk cutter mounted'on the top of the applying roll, and a smaller diskcutter i which cooperates with the first-named cutter and is driven from the applying roll.

These and other features of the invention 1ncluding certain details of construction and combinations of parts will be described as embodied in an illustrative machine and pointed out in the accompanying claims.

Referring now to the accompanying drawlngs,

Before proceeding to'a detailed description of the machine, a short description of its general mode of operation will be giveni Referring first to Fig. 1, the shoe 100 on its last 200 is supported in a holder the upper and lower parts of which are carriedrespectively by alined vertical shafts 21, 22; and, in the operation of the machine, these shafts are rotated to impart a little more than a complete rotation to the lasted shoe. During this rotation a foxing applying member 23 (Fig.

6 are similar'to Fig.

7 isa sectlon on the line VIIVII of more particuthe foxing area, the application being made through a belt 24 which runs over the roll and carries the foxing. Due to the longitudinal curvature of the bottom of the shoe, the foxing area at the heel end of the shoe is at a different level from that at the toe end. In order, therefore, to cause the foxing to be applied properly, it is necessary to produce at the proper times relative movement between the shoe and the applying member.

of the shoe,that is, from the heel end to approximately the ball linewhile the shoe is in the positionshown in Fig. 1; and, when the forepart is reached, theshoe 1s rocked or tilted forward into the position shown'in i Fig. 2 and remains in that position while foxing is applied around theforepart.

The'mechanism for holding and rotating the shoe comprises, as has been explained, the

alined shafts 21 and 22. The shaft 22 is mounted in vertical hearings in the frame of the machine and vhas fast toits upper end a hub 25 rigid with which is a bar 26 (Figs. 1 and 4). At one end of the bar is a support 27 for the rear part of the;shoe, said support being connected with the bar by a pm 82 which extends into an fupwardly extending slot in the. support. 7. The bar 26 passes through an elongated vertical slot in the sup port 27 so that the support may be'pushcd up at any time to rock the shoe. At the other end of the bar 26 is a support 28 for the'forepart of the shoe, said support being slidably mounted on thebar by screws 29 whichpass through downwardly extending flanges on the support 28 and, through anelongated horizontal slot in the bar. A spring 30, located in the slot in the bar, urges the forepart support 28at all times to'the right, as viewed in Fig. 1. As shown in that figure thesupport 28 is being held in place by the forepart of the shoe, which is clamped to it. Ifthe shoe were removed, the support. 28 would move to the right until arrested by contact of one of the screws 29 with the end of the slot in the bar 26. In Fig. 4 is shown a plan viewof the bar 26 and the supports 27 p and 28. It should be noted that the forepart support 28 has two upstanding corrugated or toothed ridges .31 upon which the locality in the ball line of the shoe rests.

In Fig.1,the shoe is shown held firmly between thealined shafts 2 1'and 22 and with the common axisof the shafts 21, 22. To this end the pushers are attached respectively to slides 35, 36 mounted on horizontal rods 37 and normally held apart by springs 39. Chains 40, 41, attached at their upper ends to the slides 35, 36, pass over-suitable pulleys, and are connected at their lower ends to the upper end of a spring 42, the lower end of which is connected about midway between the ends of a treadle rod 43 pivoted at 44 and having a treadle 45. The operation of this shoe centering mechanism is as follows: Assuming that that part of the shoe holder (not yet described) which is associated with the shaft 21 is in raised position, the operator places the shoe upon the supports 27, 28, and depresses the treadle 45. The pushers 33, 34 thereby engage the toe and the heel of the shoe and center it with respect to the common axis of the shafts 21, 22; and during this centering movement an auxiliary pusher 47 associated with the toe pusher 33, engages the forepart support 28 and pushes it back against the force of the spring so that it will be well out of the path of the foxing applying mechanism. When the shoe has thus been centered, the upper part of the shoe holder is brought down into the position shown in Fig. 1 to hold the shoe firmly in.

place.

The upper part of the shoe holder is in effect a clampor jack having a small contact member 48 (Fig. 2) adapted to engage the toeportion of the upper of the shoe and a narrow plate 49 adapted to engage the top ofthe last. The toe member 48 is fast to a stem 51 which is threaded into a downwardly projecting cylindrical portion of a block 52, said block being slidable on a-bar53 and held in adjusted position by aset screw 54. When the shoe is rocked forward from the position shown in Fig. 1 to that shown in Fig. 2, it also rocks slightly sidewise, due tothe transverse curvature of the bottom. of the shoe. In order to permit this sidewise rocking, the last engaging plate 49 is supportedat its forward end on the head of a screw 55 which is threaded into the forward extension of a block 57, said block, like the block 152, being slidableon the bar 53 and held in adjusted position by a set screw 59. The hole in the forward end of the last engaging plate 49 is larger than the stem of the screw 55 so that the forward end of the plate is merely extending ears, one of which is shown at 61,

to engage the sides at the top of the last. With this construction the slight sidewise rocking of the shoe, which has been referred to above, is permitted since the plate 49 can move somewhat with respect to the block 57.

In order to facilitate such movement, a ball.

so to rock, while the, shoe is still held firmly clamped, the bar has an upstanding lug (Fig. 1) fastenedby apivot screw 63' to a downwardly projecting lug on a slide 64 having rolls 65 which run on the ledges of an undercut guidewayin an upwardly inclined guide member 66. A spring 67, located in the guideway tends to holdtheslide 64 in the position shownin Fig. 1 against a stop, not shown. i i,

The guide member 66 has projecting upwardly from it a boss in a socket in which the lower end of the shaft 21 is fastened by a pin 69. The shaft 21 is rotat-ably and slidably mounted in avertical bearing formed in an overhanging arm 70 of the frame of the machine and is at all times urged upwardly by a coiled spring 71 which rests at its lower end upon the overhanging; arm 70 and at its upper end engages the under side of a washer 72 which is loose on the shaft 21.

Above the washer and separated from it by a ball thrust bearing (not shown) is a sprocket which is fast to the shaft 21; and around this sprocket, as well as around a sprocket fast to the upper end of ashaft 73, runs a chain 74, through whiclnas will presently appear, the shaft 21 is rotated from the shaft 22. Located above the sprocket on the shaft 21 is a second ball thrust bearing (not shown) and a second washer 75-the top of which is above the top of the shaft. Resting'upon this washer is a cap-piece 76 having a cylindrical stem which is loosely received in a cylindrical socket in the top of the shaft. Fastened to the cap piece by a screw 77' is the upper end of a cord 78 which runs over guide pulleys 79, S0 and is attached at its lower end to the upper end of a spring81, the lower end of which is attached to atreadle83. Thespring 81 is stronger than the coiled spring 71, which encircles the shaft 21 ;-and.consequently, when the treadle 83 is depressed, as it is shown in Fig, 1,, the shaft 21 is moved down to cause the shoe to beheld firmly against the toe and heel supports 27, 28. The treadle 83 is held depressed by a lug 163 during the rotation of the shoe and the laying of the foxing. After the laying operation has been finished, the

treadle 83 is swung out from. beneath the lug 163, whereupon the coiled spring 71 raises the shaft 21, and with it the upper shoe clamping members so that the shoe may be removed from the machine.

It has been stated above that the shoe, during its rotation, is rocked or tilted from the positionshown in l to that shown in Fig. 2 and back again. To this end (Figs. 2,

4 and 9) the hub at the upper end of the vertical shaft 22 has an' extension, in a hori-- zontal bearing in which is rotatably mounted a short shaft (Fig. 9 having integral with its outer end a crank arm 87 in which is fastened by a'pin 89 a short spindle 90. Upon this spindle are-two rolls 91 and 92. The roll 91 runs, during a part of the revolution of the shoe, on a cam track shown in detail in V Fig. 9. The roll 92, which is of. slightly greater diameter than the roll 91, engages the under side of the heel support 27, when the ro1l91 rides up on the cam, and thereby rocks the shoe forward from the position shown in Fig. 1 to that shown in Fig.2; and, when the roll 9lrides down and off the cam, the shoe is permitted to rock back into the position shown in Fig. 1, under the influence'of the spring 67 which is compressed when the shoe is rocked forward. I r Before proceeding to a description of the construction of the cam with which the roll 91 cooperates, it should be explained that the change in level between the rear portion of the foxing area on the shoe and the forward portion is gradual on the outer side of the shoeand comparatively abrupt on the inner side of the shoe. In the illustrated machine the laying of the foxing beings at a point in the locality of the heel breast line on the far side of the shoe as viewed in Fig. 1 and takes place progressively first around the heel end of the shoe, then along the side exposed to view in Fig. 1 and thence around the toe back to the point of beginning. At thefstart-,'the

shoe is'always held in the position shown in Fig. 1. If the shoe is a' right shoe, as shown in the figure, the foxing applying member will encounter first the gradual change in level of the foxing area on theouter side of the shoe and afterward the more abrupt change on the inner sideof the shoe. If, however, the shoe is a left shoe, the foxing applying member will encounter the more abrupt change in level first; and thegradual change last. It is thus necessary to provide two camsor what amounts to two cams-to cooperate with the roll 91, one for right shoes inwhich the gradual rise comes first andthe abrupt descent last, and theother for left shoes in which the abruptrise comes'first and the gradual descent last. To this end the cam (Fig. 9) is made in two parts 93 and 94, the part 93 being fastened by screws 95 to the frame of the machine, and the part 94 being slidably mounted upon the part 93 by means of screws 96, which pass through slots 97in the part 94 and are threaded into the part 9 3. The high portions of the parts are'substantially flat and at the same level.

The part 93 has comparatively abrupt inclines at both ends.- The part 94 has comparatively gradual inclines at both ends.

With the parts inthe positions shown in Fig. 9 in which the part 94 occupies its right-hand position, the roll 91 will first run up the gradual incline on the part 94 and finally run down the more abruptfincline on the part 93,

the parts being in'position for a right shoe;

If now a left shoe were to be operated upon the part 94 would be shifted'to its left-hand position so that the roll 91 would first run up the abrupt incline on the part 93 and finally run down the gradual incline on the part 94. In order to facilitate adjustment of the park 94 there is mounted on it a springpressed locking pin 98 the end of which is adapted to be held in one or the other of two holes formed in the part 93. One of these holes is indicated at 99 in Fig. 9; the other is occupied by the pin. v

The shaft 21 (Fig. 1) is driven from the shaft '22 through thechain 74, theupright shaft 73 and a second chain 101 which runs over a sprocket on the lower end of the shaft 73' and oveifanother sprocket on the lower end of the shaft 22 The shaft 22 (Fig. 7

is driven from an upright shaft 102 byia chain 103 which passes around a sprocket 104 onthe shaft 22, over a tightener pulley 105 and around a'sprocket 106 on the shaft 102.

The tightener pulley 105 is carried at the worm gear 110which is driven continuously by a worm 111, the'worm being fast to'one end of a horizontal shaft 113 to the other end of which apulley 114 is fast, said pulley be-.

ing driven continuously from any suitablev source of power, as for example the motor shown in Fig. 1. The gear 110 rotates on a downwardly extending. sleeve which is rigid with the sprocket 106; and may be clutched to the shaft 102 by moving upwardly a clutch member 115 which is slidably keyed to the shaft. groove to receive rollers, one'of which is shown at 116 (Fig. 7) mounted in the arms of a forked lever 1 17 pivoted near its middle at 118 to the frame of the machine and at its outer end to the upper end of a treadle rod 119 which may be pulled down at any time by depressing a treadle 120 to which the lower end of the rod is connected.

The operation of the machine as thus far described is-briefiy asfollows: Assuming that the treadle 83 is released and that consequently the shaft 21and the upper clamp- This clutch member has the usual ing member carried by it are in raised posishown in Fig. 1 in which theshoe is firmly held against the supports 27 and 28 by the member 48 which engages the toe portion of the shoe and the plate 49 which engages the top of the last. The treadle 1 20 is then depressed to impart rotation to the shafts 21 and 22 and is released when the shoe has com- 'pleted slightly more than one revolution so thatthe ends of the applied foxing will overlap. The applying of the foxing starts, as has been explained, at about the heel breast line on that side of the shoe which is hidden from view in Fig. 1. During the rotation of the shoe and the applying of the foxing, the heel support- 27 remains as in Fig. 1 until the foxing has been applied around the heel end of the shoe and well toward the ball line on that side of the shoe which is exposed to view in Fig. '1. At this stage of the application of the toning, the roll 91 runs up and over the stationary cam 94, 93. The rise of the cam causes support 27 to be raised and the shoe to be rocked into the position shown in Fig. 2. The flat, high part of the cam holds the shoe in this position while the foxing is being applied around the forepart of the shoe; and thenthe descending'part of the cam permits the shoe to be rocked back into the position shown in Fig. 1 and held there while the fox'ing is applied from the locality of theball'line to the point of beginning. It should be particularly noted that the shoe is held firmly in all positions to which it is tilted, the slide 64 moving up in the inclined guide 66 (Fig. 1'), and the plate 49, which engages the top of the last, rocking slightly from side to side.

Referring now more particularly to Fig.2, the mechanism for guiding the foxing to and pressing it against the foXi-ng area of the rotating shoe will be described. As has been stated. the foxing applying member is the roll 23 around which passes the belt 24, a strip of foxing 300 of the proper length being laid upon the beltand conducted to the shoe. The applying roll 23 is rotatable upon a small upright spindle mounted at the outer end of the arm 121, the inner end of which has a hub rotatably mounted upon an upright spindle 122, said spindle being fastened by a set screw 123 in a socket formed in an upwardly extending cylindrical boss on an arm 125 (see also Fig. 8). A torsion spring 126, fastened atits upper end to the hub 6t the'a rm 121 and at its lowerend to the boss urges the arm 121 at all times-toswingtoward the shoe. Fast to the arm 121 is one end of a twisted bar 127, from the other end of which is suspended by an upright bar 128 the horizontal spindle, upon which a roller pulley 129 is rotatable. The belt24, which has been referred to above, passes around this roll and around the applying T011323; and

this belt is driven by contact'with the moving shoe.

As the foxing is laid progressively along the foxing area of the shoe, it is desirable that it should be pressed into firm contact with theshoe. To this end a presser 130, in the form of an inflated rubber'roll, traverses the foxing area closely'behind the applying.

roll 23. The presser roll is carried at the outer end of an arm 131 having a hub which, like that-of the arm 121, is rotatable upon the upright spindle 122 and is urged at all times to swing toward the shoe by a torsion spring l32, fa'stenedat one end to the hub of'the arm 131 and at the other to a sleeve 133 which is fast to the stationary spindle 122. A brace 134, rigid with the spindle-supportingarm 125, has acylindrical boss at its upper end through which the spindle 122 passes, a set screw 135 being threaded through the boss into contact with the spindle. Located adjacent to the top of the applying roll 23 in position-to trim the upper edge of the foxing before the :toxing is applied to the shoe, is aitrimming mechanism consisting of two cooperating disk cutters 169,170; and also located adjacent to the top of the roll in position to act upon the fox-ing after it has been applied to the shoe is an indenting or so-called stitching wheel 164. Both the wheel and the mechanism are mounted upon the arm 121 and will be described later in detail. Due to the presence of the wheel and .the mechanism, it is desirable that a substantially fixed relation be maintained between the spindle or carrier 122 and the roll 23, on the one hand, and, on the other hand, the locality on the rotating shoe at which the toxin-g is being applied, so that the applying roll will alwaysoccupy a position, such'as that'shown best in Fig. 2, in which the trimming mechanism 169, 170 is out of contact with the shoe, and the indenting wheel 164 operates upon the foxing just after the foxing has been applied. The objectionable result which would ensue upon changing this enough. a The desirable relation referred. to

vabove is in general that the s indle orcarrier 122, in all its positions, shou d be well ahead A of the foxing and a plane passed through the aris ofthe roll 23 and the axisof the spindle 122 should always be an acute angle of substantially uniform size. Referring to Fig. 3,

the two planes are indicated respectively by the dash lines A and B, the angle between them, in, the illustrated construction, being of the orderof about thirty'degrees.

It is obvious that, if no" provision were made to maintain this relation, ;it would be disturbed most'when the. applying roll was moving around (so to speak).,the toe or the heelof the shoe. The illustrated mechanism for moving the spindle or carrier 122 is, constructed and arranged to move the carrier ina manner to preserve. the relation which hasbeen described aboveand particularly to accelerate the forward movement of the carrier when foxing is being applied around the heel and around the toe of the shoe. Figs. 5 and 6 illustrate this accelerated move,- ment. In Fig. 5 the applying roll 23 is approaching the toe end of the: shoe; in Fig. 6 it has passed the toe end. The extent of movement of the applying roll from the position shownin Fig. 5 to that shown in-Fig. 6 is small; but it will be noted that in the same interval the spindle 122 has moved a much greater distance. Referring now to Fig.4, which shows substantially the position in which the application of the foxing begins, thespindle 122 moves in the path of a very much elongated figure 8, the -lon'g axis of which is substantially perpendicular to the longitudinal axis of the shoe in the position occupied by the shoe in that figure, the movement of the spindle being accelerated at the curves at thetop and bottom of the-figure 8 path for the purpose which has been described above.

Referring now more particularly to-Fig. 2-with occas'ionalreference to'Figs. 3 to 6, the-spindle 122, as has'been explained, is carriedat the outer end'of an arm125. This arm is pivoted at its inner end at 136 to an extension on'a main arm 137. This'main arm is pivoted at its outer'end about a stud 138 carried by a crank arm 139 which is fast to the upper end of the shaft 102 from which, as has been explained, the shoe is rotated. The other end ofthe main arm 137 is formed with two spaced guides which "run in horizontal guideways formed in a block l40, which is loosely carried near the upper end of the shaft22 upon which the shoe is supported. The stud orpivot 138 is fastened to the outer end of the crank arm 139; and also fast to this stud is a short arm 141 so vthat the two arms' 139 and'141 are in effect one piece. -The arm 141 is-connected 'with the upright spindle 122 byanextensible link shouldered stud, the upper; end 1430f which is of reduced diameter and threaded. "A gear 145 has a hole to receive loosely. the threaded, reduced portion 143 of the stud and is clamped to the shoulder of the stud by a nut147 so that the gear is rigid with the arm 141. V Rotatable on the stud and located between the gear 145 and the arm 141 is one end of the upper member 148 of a two-part extensible link, best-shown in Fig. 8,'said member 148 being slotted as shown in Fig. 2; Below the upper member 148 of the extensible link is the lower member 149, one end of which is rotatable upon the upstanding cylindrical boss of the arm 125. This lower'member has-a guide stud 150 (Fig. 2) which extends up into. the. 'slot in the member 148; and'the two'me'mbers are slidably held together by a screw 151 which passes through the slot and is theraded into the lower member 149. Inorder toextend the link at the proper times, a gear 152, which is rotatably'mountedupon the upper member 148 of the extensible link and meshes with the gear 145, has a crank ipin 153 on which is pivoted one end of a connecting rod 155, the other end of said rod being pivoted on the upper" reduced end of a stud 154. carried by the lower member 149 of the extensible link. A screw 156 holdsthe end of the connecting rod 155 on thestud 154. When the shaft 102 is rotated in the direction indicated by the feathered arrows in Figs; 5' and 6, the gear '145, which is rigid with the arm 141 and thearm 139, moves in an orbital path about the axis of said shaft and causes the gear 152 to make one rotation in the direction indicated by the plain arrows, for each com plete orbital revolution ofthegear 145. At each rotation of thegear152, the extensible link, made up of the parts 148,149, is completely extended and completely contracted.

Theshaft 102 (Fig. 7), owingto the fact that the diameter of the sprocket 106 is one-half the diameter ofthe sprocket 104, makes tworotations for a single rotation of the shoe. The link is, therefore,jextended:twicefor each rotation of the shoe, and these extensions are timed to take place respectively when the foxing is being applied around the heel end and around the toe end'of the shoe. In order to steady the outer end of the arm 125, said outer end runs in a guideway 176 (Fig. 2)- formed in'afbar177 which is 1 fast'to the frame of the machine.

It is desirable that the foxing'applying and pressing members should be automatically withdrawn fromthe shoe when'the shoe is'released preparatory to removing a shoe from the machine andlthat said members should be automatically moved. into operative 1 position when a new shoe is clamped in place in the machine. To this end a. cord 157 (Fig.- 4), fastened at its upper end to the twisted bar 127 which is fast'to the arm 121 by which the foxing applying member is carried, leads over a pulley 158 and down to one end of a lever 159 (Figs. 1 and 13). This lever is pivoted near its middle at 160 to the frame of the machine; and at its outer end is connected by a link 161 with the treadle 83. A tension spring 162 connects the inner end of the lever 159 with the frame of the machine. In the position of parts shown in Figs. 1 and 13, the lever 83 is depressed and held down by a lug 163 beneath which it has been swung. The cord 15'. is slack at this time, and the foxing applying and pressing members. are being held against the shoe by their respective springs. When, at the completion of the operation upon the shoe, the treadle 83 is swung from beneath the lug 163 and permitted to be pulled up by the springs 81 and 162, the lever 160 will be rocked in a counterclockwise direction as viewed in Fig. 13, whereby the cord 157will be pulled down and the carrier arm 121 (Figs. 2 and 4) of the foxing applying member swung away from the shoe. The arm 121 will engage the carrier arm 131 so that both the foxing applying member and the presser will be pulled away from the shoe. The operator now removes the shoe which has been operated upon, places a new shoe in the machine, depresses the treadle 83 once more and looks it in depressed position. The parts are then again in the positions shown in Figs. 1 and 13 with the cord 157 slack and the foxing applying and pressing members in o erative positions.

It is desirable to press the upper edge of the foxing firmly into contact with the shoe by running an indenting wheel along said edge. In the illustrated machine, such a wheel 164 (Fig. 1 which has been referred to above, is rotatably mounted at the outer end of an arm 165 which is pivoted at 166 to the arm 121 by which the foxing applying roll is carried. A spring 167 holds the-arm 165 against the shoe. As fast, therefore, as the foxing is applied to the shoe it is indented along its upper edge by the wheel 164. The extent to which the arm 165 can be swung toward the shoe about its pivot 166 by the spring 167 is limited by reason of a stop (not shown) on the arm 121 with which a part of the arm 165 contacts.

It is very desirable that the upper edge of the foXing in the finished shoe shouldpresent a smooth, unbroken line and not a wavy one. In order to ensure that any unevenness in the width of the foxing or any slight displacement of it on the belt 24 shall not result in a wavy edge at the top of the foXing in the finished shoe, means are provided for trimming-the upperedge of the foxing.

To this end two coo eratin disk cutters a P e 169, 170 (Fig. 12) which have been referred to above are provided. The cutter 17 0 is fast to the lower end of a small stem 171 which is rotatable in the end of an arm 172, said arm being integral with or fastened to the arm 121. The disk cutter 16 9 is clamped to the top of a sleeve269 (Fig. -2)'which is rotatable upon an upright spindle carried bythe arm 121, the cutter 1 69 being held down in contact with the cutter 170 by a coiled spring 271 the upper end of which engages the under side of a washer, said washer being fastened to the top of the upright spindle by a screw 273. The sleeve 269 is driven from the applying roll 23 Fig. 12) by means of a gear 173 fast to'the lower end of the roll which meshes with a smaller gear 274 fast to the lower end of the sleeve. Thus, whenever the foXing applying roll is rotating, the cutters 169, 170 are also rotating" and serve to trim the upper edge of the foxing. In order to guide the foXi-ng properly tothe trimming cutters 169, 170, an upright.

guide roller 174 for the carrier belt 24 .is provided. In this connection, it should be noted that the belt 24 has extending along its lower edge a ledge 175 (Fig. 2) upon which the lower edge of the foxing rests when passing to and around the applying roll 23.

The complete operation of the machine is i briefly as follows. Assuming that the treadle 83 (Fig. 1) is released, in which case the upper clamping member for the shoe will be in raised position and the cord 157 will be The pressed position, and the treadle released.

Depression of the treadle 83 moves the shaft 21,'with its attached shoe clamping members down to clamp the shoe firmly in place, and at the same time allows the cord 157 to become slack so that the torsion springs 126, 132 (Fig. 2) may swing the foxing applying and pressing rolls into operative position. A strip of foXing of the proper length is placed. upon the belt 24 and the treadle 120 depressed and held down until the shaft 102 has made two revolutions and a fraction, whereupon the shaft 22, which carries the shoe, makes slightly more than one revolution. The upper edge of the foxing is trimmed by the small disk cutters 169, 170 just before the foxing is applied to the shoe;

and, just after it has been applied, it is in? A into place by the inflated rubber presser Although the invention has been set forth as embodied in a particular machine, it
